Abstract
The invention provides a laser quenching treatment method for a corrugator roll, which comprises the following steps of: (1) preparing phosphating solution; (2) performing phosphating on teeth of the corrugator roll by adopting the prepared phosphating solution; and (3) performing laser scanning on the corrugator roll by adopting a laser, aligning laser spots of the laser with the tops of the teeth of the corrugator roll, and axially scanning each tooth top according to a symmetrical sequence until all tops of the teeth are scanned. Due to the adoption of the symmetrical scanning technology, the laser quenching treatment method has the advantages of low axial deformation, long service life, wide application range and the like, and can achieve a dispersion-strengthening effect under an environment of rapid heating and rapid cooling of the laser.

Description
Technical field
The invention belongs to metallic substance LASER HEAT TREATMENT and light industry and make field, particularly a kind of corrugated roller laser quenching treatment process.
Background technology
The corrugation roller is a most important component in the corrugation paper mold production unit, for the corrugated paper board production line of any class, and one of easily worn part that the corrugation roller is always the most expensive.For any type of corrugation roller, it all has same basic functions of use and abrasion mechanism.Corrugating Base Paper is in the flatiron bending forming process that joint advances at a high speed, continuously, under the linear pressure effect constantly with the relative displacement of the stupefied jacking row of corrugation roller and produce that friction is crowded rolls, be subjected to the bump that rolls of the inclusion that contains in the body paper and mineral solids, make the stupefied top of corrugation roller that sharp wear take place, and wear into irregularly shaped gradually by circular arc, continuously run up, stupefied tooth height is step-down slowly, makes the cardboard of production tend to standard min gradually.Therefore the corrugation roller that some stupefied surface hardness are low also can make stupefied of stupefied top produce pockmark and depression, has aggravated the wearing and tearing process.Because production line often is not often to expire width of cloth paper feed, causes corrugation roller surface to produce uneven wear and cause corrugation roller concave and cause the foaming of coming unstuck in the middle of the cardboard.Soft corrugation roller under the monodentate of continuous high speed engagement direction operation situation also can because of viscous deformation take place stupefied, tilt, distortion, increase ovality and runout error, accelerate to influence the work-ing life and the economic performance of corrugation roller.Therefore, the corrugation roller generally needs to make it can satisfy production requirement through medium frequency quenching or nitriding treatment aborning.
Medium frequency induction hardening process commonly used at present has following shortcoming: (1) exposes heating because medium frequency quenching belongs to, unavoidable oxidation, decarburization, and hardness is low, and anti-fatigue performance is also poor; (2) because heating in medium frequency needs the reinforcing degree on the stupefied top of emphasis reinforcement do not need to be not so good as the too strong stupefied end, the performance paradox takes place; (3) though medium frequency quenching has the thicker advantage of strengthening layer, therefore produce bigger distortion, the deflection (diameter run-out) of medium frequency quenching corrugation roller is 0.1～0.15mm, and subsequent handling is caused very big difficulty; (4) another negative impact that the medium frequency quenching strengthening layer is thicker is to quench after old roller is repaired again, because quenched case is not removed fully, causes the part to repeat to quench, and is easy to generate crackle.Therefore during medium frequency quenching corrugation roller only is applicable to, the low speed production line.Medium frequency quenching corrugation roller is 8,000,000 to run about rice work-ing life.
Another kind of wolfram varbide corrugation roller, its wear resisting property is superior can't deny, but there are many difficult points in the application of wolfram varbide corrugation roller: 5～6 sprayings of wolfram varbide corrugation roller needs just can reach the thickness about 0.1mm, grinding and polishing then, real work thickness is 0.05～0.06mm, and the rate of recovery of sprayed wc only is about 30%; Owing to need reconditioning again, polishing after the wolfram varbide spraying, and wolfram varbide is very hard, can only grind with diamond abrasive tool, so the grinding cost is higher; In addition, present sprayed wc can only carry out on the matrix below the HRC45, though coating is wear-resisting, but matrix is softer, thereby be unable to undergo gravel and roll, under the relatively poor condition of papery, use and be easy to occur pockmark and depression, so wolfram varbide corrugation roller can only have high end equipment and use under the high-grade body paper condition and use, subject range is mainly at high-speed production lines and the few high-grade body paper of use sand content, and the market environment characteristics of China are in being more than 80%, low-speed device, therefore its space in Chinese corrugation roller market is also less relatively, even abroad, and neither widespread usage.
Summary of the invention
